[FEATURE]: Run Id should be available in a process

[themasterlink]

While using bbopt each run process has its own run id, which is not available during each run.

It would be awesome if the run id can either be accessed via the BlackBoxOptimizer object or via an environment variable, which has to be then set for each process.

@themasterlink Thanks for the issue! This should now be available as bbopt.run_id on bbopt>=1.3.7.
